Packera glabella (Butterweed)
Flaigg, Norman G.

Packera glabella (Poir) C. Jeffrey

Butterweed, Cress-leaf groundsel, Yellowtop

Asteraceae (Aster Family)

Synonyms: Senecio glabellus

USDA Symbol: pagl17

USDA Native Status: Native to U.S.

An upright, smooth, succulent annual, 18-20 in. high. Stout stems may be branched or unbranched and are topped by a large, cluster of yellow, daisy-like flowers. Interesting leaves are deeply-divided in rounded segments or lobes and become smaller toward the upper portion of the plant. Usually forms large colonies in the moist-to-wet habitat it prefers.

Though an annual, Packera glabella usually seeds out so densely that it achieves the same groundcover effect as many of the perennial Packera species. Unlike some of those better known perennials, this species can bloom in either sun or shade, as long as it is situated in a moist site. The leaves emerge in the fall and add low winter green to the landscape. Blooms are profuse, filling its colonies with yellow throughout the spring months.
